The super DJ was at Pearson International Airport in Canada yesterday ... when he was asked about the Madonna thing ... and he replied, "How is it?! It's terrible."

As we previously reported, Deadmau5 had accused the singer of promoting drug use at a recent electronic music festival ... but Madge fired back, claiming he totally misinterpreted her comments ... and scolded him for not addressing his gripe privately.
